If you need a tire that can handle the rigors of training and stand up to the demands of racing, the Vittoria Diamante Pro Special Edition road bike tire has got your back. This Nashbar Exclusive has a high puncture resistance, low rolling resistance and it corners like a boss.

I've reviewed these before. Now I have 12,000 miles on three sets of Diamantes, I am even more enthusiastic. First, a great, smooth ride. Second, very low rolling resistance (I pass most other riders in my club freewheeling on downhill stretches). I've had seven flats during those rides--I rate that as excellent. Next tires will be Diamantes but I will upgrade to the new Graphene series. Those could be real game changers.

This is my first switch from 23 to 25. I use this tire on my training bike. I wanted a tire that felt as fast as my racing 23 tires but was more forgiving and had better grip in varied conditions. This tire exceeded my expectations in both areas. The additional 2mm greatly increased comfort, the center hard, flast strip kept it a fast tire, and the softer grooved sides made a big difference in cornering. And on top of it all, the two tone color scheme looks fantastic.

I ride 3-4 times a week averaging over 100 miles. From the first several uses, I would anticipate excellent wear from these tires, much better than the Bontrager's that I had been using. The jury is still out on the performance of the tires, but so far so good.

Fantastic tires; they handle like a boss , the ride is excellent , they where easy to mount ! After reading the other reviews i read the instructions and took my time mounting them . Love them , will buy again . I have a friend who has 3 years on his set , and there still ok .
